Digizo Portable DVD Player - Design Priciples vs Quality/Price
Introduction
It is a mobile multi-finction DVD player with swivel 12.3" high definition screen from Digizo.co.uk that can fulfill the entertainment needs. The DVD player is not only multi-region with compatibles formats, but as well as recording Freeview TV channel with a built-in analog and digital Freeview tuner. It is also can be used as a game console that support NES 8-digital game function, provided with the control pad. To add more features to this, the manufacturer has designed it with Super Strong anti-shock system, with the playback VGA input function and supporting SD/USB. Together with the price of GBP199.00, this product is a must buy.
Design Principles to Manufacture the Product
Most of the portable DVD players in the market do not have the features that this product has. The 180 degrees swivel TFT (Thin-Film Transistor) screen will help customers to watch DVD from any angle. Here, it clearly shows the flexibility that would give comfort to customers when buying this product. Personally, I own a portable DVD player that I bought about a year ago. It has some of the features that this product has respectively, for the price less than GBP100.00. But the clever design of making the screen swivel for 180 degrees, which mine does not have, makes mine so outdated and less comfortable. Besides increasing the viewing angles for a better viewing experience at most desirable angle possible, this product essentially will help cutting down on glare. It also can be fixed in any vehicle easily.
The idea that this product can record our favorite freeview television program by simply press the Record button is excellent. Like any other recording device (like example VCR), the latest technology applied to a portable DVD player from different manufacturers will have the recording mode. But, what make this product more excellent is the quality of the recording. The fact that a DVD recorder is like a VCR that can record onto an unlimited number of optical media, the application of progressive Phase Alternating Line (PAL) digital processing (for Asia, Africa, South America, Australia, New Zealand, and some parts of European countries) with high definition format of recording, makes the recording quality and the audio clarity of the recorded program are well improved and up to standard.
The Impact of the Quality and Price Affected by the Design Principles
The fact that it can be fixed in the car easily has increased the quality of the product. Under the delay product customization steps criteria, the fact that this product can be fixed in the car easily has made it more flexibility for mass market. It also can reduce response time for custom changes by following the steps in the manual provided on how to fix it in the car.
The other design principle which it can record a freeview TV program by a single touch is an evidence that this product has a functional options. This is how the product is maintaining its independence of functional requirements. By just a touch, it will reduce the critical failures, especially for someone who is not familiar in dealing with electronic devices. It will make the process becomes easier to the users.
Comes with other accessories like example game console pad, earphone, and an antenna that can easily be plug-in and use has made this product worths the price. This shows that this product does not have any delay on product customization steps, hence it is more flexibility for mass market. At the same time, it reduces response time for custom changes and the impact of changes in different markets. So, clearly this product gives impact to the price from its simple design principles.
The manual instruction provided together with product will make the usage of the portable DVD player becomes easier. This is because the manual used simple and clear instructions with some diagrams for convinience. Since the product itself its not difficult to install, the manual actually shows that the product has minimize information content of the design. This will help to minimise errors, and will make the product easier to sell.
